Application executing method using fingerprint recognition, device therefor, and computer readable recording medium therefor

1. An application-executing method using fingerprint recognition, comprising: receiving a first fingerprint image and recognizing the first fingerprint image; executing a first application corresponding to the first fingerprint image in a first screen upon recognition of the first fingerprint image; receiving a second fingerprint image and recognizing the second fingerprint image; determining whether the recognition of the second fingerprint image is performed within a predetermined time, the predetermined time being started subsequent to the execution of the first application; and in response to the determination of the recognition of the second fingerprint image, upon the second fingerprint image being recognized within the predetermined time, operating a second screen by splitting the first screen, wherein, the second screen, split from the first screen, displays a second application corresponding to the second fingerprint image, and the first screen, not including the second screen, displays the first application corresponding to the first fingerprint image, and the second screen is separately displayed apart from the first screen.

2. The method according to claim 1 , further comprising: in response to the determination of the recognition of the second fingerprint image, the recognition of the second fingerprint image exceeding the predetermined time after the execution of the first application, stopping the execution of the first application and executing the second application on the first screen.

3. The method according to claim 1 , wherein the second screen is operated by splitting the first screen horizontally in half.

4. The method according to claim 1 , further comprising: before the obtaining of the image of the first fingerprint, storing user-setting information that allows the first application to be executed when a first fingerprint is matched with the first fingerprint image, and allows the second application to be executed when a second fingerprint is matched with the second fingerprint image.

5. A non-transitory computer readable recording medium for recording a computer program that executes the method according to claim 1 .

6. An apparatus, comprising: a non-transitory computer readable storage device, wherein a plurality of applications are stored in the storage device, the applications comprising a first and a second applications; and a fingerprint sensor configured to consecutively obtain a plurality of fragmented fingerprint images from a user's moving finger and recognize a fingerprint, wherein at least one fingerprint image is stored in the storage device, wherein, the first application is executed on a first screen by a processor when the fingerprint recognized by the fingerprint sensor is a first fingerprint image, and the second application is executed, by the processor, when the fingerprint recognized by the fingerprint sensor is a second fingerprint image, wherein, the processor determines whether the recognition of the second fingerprint image is performed within a predetermined time, the predetermined time being started subsequent to the execution of the first application, and in response to the determination of the recognition of the second fingerprint image, upon the second fingerprint image being recognized within the predetermined time, a second screen is operated by splitting the first screen, wherein, the second screen, split from the first screen, displays a second application corresponding to the second fingerprint image, and the first screen, not including the second screen, displays the first application corresponding to the first fingerprint image, and the second screen is separately displayed apart from the first screen.
